You and your DD's have been through a huge upheaval. I am not beginning to imagine how hard that is.
I just wanted to say that when DS (4yo) and i seemed to be at loggerheads a lot, i always put him to bed and sat or lay with him for 10/15 mins and we had this ritual where he would tell me what fun things happened that day. We rarely did anything amazing, just swings, a slice of fairy bread, finding an odd mushroom etc, but it helped me not feel like the whole day was a failure - he still had fun even if it was small. ANd i felt like we went to bed on a good note, itms?
